For a deeper understanding what drives nucleosynthesis in astrophysical scenarios like novae and x-ray bursts, p and α capture reactions with unstable isotopes are important. Radioactive ion beam accelerators like at the Facility for Rare Isotope Beams (FRIB) give us great opportunities to study these reactions experimentally. The Jet Experiments in Nuclear Structure and Astrophysics (JENSA) gas target system at ReA was constructed to take advantage of these beams at the National Superconducting Cyclotron Laboratory (NSCL) for direct measurements of α capture reactions. A recoil separator right behind the JENSA target called SEparator for CApture Reactions (SECAR) is currently under construction. Designed for a mass range of A=15 - 65 it will enhance the number of feasible reaction studies at NSCL and later FRIB.
The reaction of 56Ni(α,p)59Cu, important for X-ray bursts and recently measured at NSCL will be presented to show the current capabilities of the JENSA system. In the outlook the status of the upgrade for hydrogen operation will be discussed together with the commissioning runs of the first section of SECAR.
